Abstract :
A rather simple and low cost method of improving mixer conversion loss and the single side-band noise temperature of a receiver was proposed and implemented. As a result the single side-band noise temperature of uncooled receivers was reduced to 770 K at a frequency 115.3 GHz and to 1500 K at a frequency 210.5 GHz
